Dear Wireworkers,
I'm having a flaky problem with a motion system that I'm trying to
pinpoint, and I thought I'd ask if anyone has seen something similar.
I'm using 3 NI 7344 motion boards, UMI interfaces, and MOOG servo
controllers (don't know the model) that provide a synthetic AB
signal for my NI board encoder inputs. Once every few hours of system
operation I'll see my motion system make a radical move, because one
of the encoders is "suddenly" off by 32768 counts i.e. 2^15. I put
suddenly in quotes because I don't know if a MOOG is deciding to
give me a burst of bogus steps that an NI board is counting, or if
an NI board is getting lost. Most of the incidents occur on one of the
axes, but I've seen it less often on a few other axes. Also, there is
no single set of circumstances where this occurs in terms of what my
software is doing at the time.
Thanks for the FREE tech support,
--David Moore
